Zero Energy Building
40% reduction of direct irradiation during the Summer
The design of a ZEB starts from a climatic studio as the same as a sun trajectories studio. The project aims to reduce total energy consumption during construction as during use. The project is divided in four categories: Sun, Water, Land and Air. The main category is the Sun and it’s focused on understanding how direct radiation can influence heat gains, both in winter and in summer. The strategy adopted to reduce cooling consumption is to create shadows on the south facade in order to shade many parts of it.
Working with lateral sections to define the right projection length calculating where the shadows will fall during the equinoctial cycle. We have found a solution consisting of three level of shadows in agreement with J. Aronin studies, father of the environmental architecture.
To prove its effectiveness, our patented solution has been used in studies comparing two other similar buildings. The first study, a focus on winter solutions, proves there are no limitations with our system while there is a significant difference between the two buildings during the summer as our system provides an extra 40% overall energy saving compared to a modern insulated building.
